Can a finiancing company put down that my car has been repossed for 2 years when it hasnt?

I went 3 months without making a payment on my car because my card got cancelled. I did forget that I needed to switch the payment information over, but the financing company never called, didn't send any statements nothing until I physically called to figure out what was going on. Basically its years later and when I'm trying to trade this car in, I cant because they have it on my credit report that the car has been out for repossession for 2 years! I called the company and they are being rude and will not work with me. Although I'm all caught up on payments and have paid every month since that first initial payments missed. Just wondering what actions I can take against a car financing company who is doing shifty business tactics, and every time you call you get a different answer on what happened.
